Serial No. 557,633.

To all whom it may concern:

Be it known that .l, Amman H. S. SWAN, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefullmpioven'ients in Alcohol- Vapor-Lamp Burners; and I hereby declare thefollowing to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming a part of thespecification, and to the reference numerals marked thereon.

My present invention has for its object to provide a burner for lampsadapted particularly for generating gas from light hydrocarbon oils, oralcohol, whereby the volume of the gas generated may be varied accordingto the intensity of the flame desired.

My invention has for its further object to provide a suitable supplyvalve whereby the flames of the main and pilot burners may besimultaneously adjusted to vary the intensity of the latter inproportion to the size of the former.

To these and other ends the invention consists in certain imprmei'nentsand combination of parts, all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings: Figure 1 is a vertical sectional view of a lampprovided with a burner showing one embodiment of my present invention;Fig. 2 is an enlarged sectional view showing the regulating valve in theopen position; Fig. 3 is a horizontal sectonal View taken on the line 3*3* in Fig. 1, and Figs. 4 and 5 are sectional views showing modifiedconstructions.

Similar reference numerals in the several figures indicate similarparts.

My present invention relates particularly to burners adapted to burn thegas supplied thereto from a suitable generator, preferably a tube 1,closed at its upper end, as indicated at 2, and containing a wick 3,absorbing the oil from the bottom of the font 4.

The burner is supported upon the wick tube, shown in Fig. 1, andcomprises the annular ring 5 provided with flame orifices (l in itsupper surface, and supported on a plurality of tubes 7, which conductthe gas thereto from the main gas collecting chamher '8. The latter isconstructed in the form of a ring which is rigidly connected to the wicktube and surrouiul'ing the latter is a similar tubular ring 9 supportingthe pilot flames, which are emitted from small orifices l0 situated atvarious points on said ring 9. The upper surface of the ring 9 in theareas surrounding the orifices 10. is depressed slightly at an angle, asindicated at 11, to cause the flames ejected from the orifices toimpinge against the wall of the wick tube for the purpose of maintainingthe tube heated to the temperz'iture necessary to supply the quantity ofgas required by the main burner 5 according to the varying conditionsunder which it may be desired to operate it.

The valve for controlling the flow of the gas to the chambers 8 and 9 isarranged be neath these rings and comprises the body or casing 12rigidly secured to the wall of the wick tube and provided with a centralaperture 13 communicating with the interior of the tubeand withlaterally extending passages 14 and 15 leading from the central apertureinto the chambers 8 and 9 respectively. The aperture 13 comprises twoportions of unequal diameter and from these portions lead the passages14 and 15. In the preferred construction of the valve the aperture 18 iscircular and at its inner end the walls thereof are cylindricalcontinuing outwardly a short distance from the wick tube to the point 16in rear of the passage 14, and from said point the aperture is madeconical, the diverging walls thus formed extending rearwardly beyond thepassage 15. Fitting the aperture in the valve easing, thus formed, is avalve head having the conical body portion 17 beyond which pro trudesthe cylindrical tip 18, said head being provided wit-h thelongitudinally ex-- tending passage 19, the outer extremity of whichextends laterally and opens at the part indicated by 20. The latter andthe inner end of the portion 18 are so proportioned relatively to eachother and to the positions of the passages 14 and 15, that when thevalve head is closed both the said passages will be cut off, but when itis adjusted rearwardly the passage 19 will first establishcommui'iication between the passages 13 and 15 before the passage 14 isuncovered. This enables a sufiicient quantity of gas to flow from thegenerating chamber to the supplemental burner to support the pilot lightflames before the gas is admitted to the main burner. After the mainburner has been in operation this arrangement permits the supply of gasto the main burner to be cut oil and the burning of the pilot lights tobe continued, if so desired, with sufficient intensity to maintain thegeneration of the small amount of which they require.

The outer end of the valve casing is fitted with the packing 21 held inplace by the usual gland nut 22 having an interior thread, providing themeans for longitudinally adjusting the valve head, the latter beingoperated by the rotation of the stem 23 attached thereto carrying asuitable operating handle, not shown.

In operating the burner heat from some exterior source is applied to thewick tube for a brief period until generation of gas in the upper endthereof has conn'nenced. The valve stem 23 being rotated will retractthe head 17 causing its larger body portion to be moved out ofengagement with the corresponding walls of the valve casing, thusproviding an annular chamber 2% through which the gas generated in thewick tube may pass from the port 20 into the passage 15 and thence tothe pilot light orifices 10. Now, if the burner is not required forimmediate use the pilot lights may be allowed to burn as long asdesired. The size of the passage 2 f may be varied by the adjustment ofthe valve head and thus the size of the pilot flames controlled, andwhen it is desired to use the main burner the valve head may beretracted until the extremity of its tip 18 uncovers the passage 14 tothe desired extent, and during this adjustment it will be noticed thatthe quantity of gas supplied to the pilot lights will be increased,their intensity being regulated in accordance with the volume of gasadmitted to the main burner.

In Fig. 415 the valve body is shown with the relatively large and smallportions 30-31 of its central chamber both made cylindrical and thevalve head made to reciprocate therein into and out of cooperatingengagement with the two outlet pas sages 14 and 15 While I prefer tomake the larger portion of the aperture in the valve casing conical, asbefore described, these parts may be an ranged as shown in themodification illustrated in Fig. 5. In this view the enlarged portion isrepresented as an annular recess 32, the forward shoulder 33 of whichcooperates with the outlet port of the passage 19 in the valve head l7when the latter is advanced or retracted by itsrotary movement in thevalve casing 12*.
